Fall Leaves and Your Murphy Pool — Prevention That Actually Works
Murphy's maturing trees are dropping more leaves into pools every year. Here's how to keep them out — and what happens when you don't.
Five years ago, the trees in your Murphy neighborhood were barely tall enough to shade the fence line. Now they're dropping enough leaves to fill your skimmer basket every 36 hours during October. The tree canopy in Maxwell Creek, Mustang Park, and Murphy Heights has been maturing steadily since these neighborhoods were planted in the 2000s and early 2010s, and every fall brings more leaves into pools that were designed for a younger, smaller landscape.
This isn't a problem that stabilizes — the trees are still growing. Each year brings a slightly larger canopy, slightly more leaves, and slightly more pool debris. The homeowners who manage it proactively spend 30 minutes per week on it. The ones who don't spend a full day recovering the pool in November when the cumulative neglect catches up.
What Leaves Actually Do to Your Pool
Leaves aren't just ugly floating debris. They're a chemical and biological problem:
Chlorine consumption. Every leaf in your pool is decomposing organic matter. Decomposition consumes free chlorine. A pool with 50 leaves sitting on the bottom for three days has measurably lower chlorine than one that's skimmed daily. During fall, when you might already be backing off on chlorine frequency, the additional leaf-driven demand can push free chlorine below effective levels.
Phosphate introduction. Decomposing leaves release phosphorus, which converts to phosphates in pool water. Elevated phosphates create a more favorable nutrient environment for algae. For a deeper look at phosphates in Murphy, see our guide on phosphates in your pool.
Tannin staining. Leaves that sit on the pool floor for more than 2-3 days release tannins that stain plaster. The stain mimics the leaf's shape — a brown or yellow imprint on the pool surface that doesn't brush off. Oak leaves and pecan hulls are the worst offenders in Murphy. Once a tannin stain sets, removing it requires concentrated chlorine application or, in severe cases, an acid treatment. For stain identification and removal, see our guide on pool stains in Murphy.
Filter clogging. Leaves that make it through the skimmer basket (small pieces, broken fragments) end up in the pump strainer and eventually the filter. A filter loaded with organic debris reaches high pressure quickly, reduces flow, and needs cleaning more frequently. During peak leaf season, you might clean your filter cartridge every 1-2 weeks instead of the usual monthly cycle.
Plumbing clogs. Large leaves can clog the skimmer throat, the plumbing between the skimmer and pump, or the pump impeller. A clogged impeller reduces pump output and can cause the pump to overheat.
Prevention Strategy 1: Leaf Net
The most effective single tool for fall leaf management. A leaf net (also called a leaf cover) is a fine-mesh net that stretches across the pool surface, supported by the pool coping and anchored with water bags or clips. Leaves fall onto the net instead of into the water. Periodically — every few days during peak leaf drop — you pull the net off, dump the leaves, and replace it.
Cost: $30-80 for the net. Water bags for anchoring: $10-20 for a set.
Pros: Captures leaves before they enter the water — eliminating chemical impact, staining risk, and filter clogging entirely. Easy to manage. Reusable for many seasons.
Cons: Not attractive — the net is visible and gives the pool a "closed for the season" look. Needs to be removed before swimming and replaced after. If heavy leaf accumulation weighs the net down into the water, the purpose is partially defeated — empty it before it sags.
Best practice for Murphy: Install the leaf net in mid-October before peak leaf drop begins. Remove it in late December when the last trees have finished dropping. During this 10-week window, the net prevents the majority of leaf-related pool problems.
Prevention Strategy 2: Tree Management
Trim overhanging branches. The most impactful long-term prevention. Every branch that extends over the pool is a leaf delivery system. Cutting branches back 5-10 feet from the pool perimeter reduces the direct leaf load dramatically.
In Murphy, where lot sizes are standard suburban (7,000-10,000 sq ft) and pools often sit within 10-15 feet of property-line trees, overhanging branches are common. An annual trim in September — before leaf drop starts — keeps the canopy managed.
Cost for professional tree trimming: $150-400 depending on the number and size of trees. Many Murphy homeowners bundle pool-area trimming with their annual tree maintenance service.
Consider the tree species. Not all Murphy trees are equal leaf producers:
- Live oaks: Drop leaves in spring (March-April), not fall. The volume is significant but the timing is different from deciduous trees.
- Red oaks and post oaks: Peak fall leaf drop in November. Large leaves that float and are easy to skim.
- Pecans: Drop leaves AND pecans in October-November. Pecan hulls stain aggressively. Pecans can clog skimmers.
- Crepe myrtles: Small leaf drop in fall, minimal impact on pools.
- Bradford pears: Moderate leaf drop. More problematic for their shallow root systems damaging pool decks than for leaves.
If you're planning landscaping changes, choose trees that minimize pool debris — or plant them well away from the pool perimeter.
Prevention Strategy 3: Enhanced Skimmer Operation
During fall leaf season, optimize your skimmer to handle the higher debris volume:
Use a skimmer sock. A fine-mesh sock inside the skimmer basket catches small leaf fragments, pollen, and debris that passes through the basket's openings. This keeps finer material out of the pump and filter. Empty the sock every 2-3 days during peak leaf season.
Angle return jets toward the skimmer. Point your return jet eyeballs to create a surface current that pushes floating debris toward the skimmer opening. This extends the skimmer's effective reach across the entire pool surface rather than just the area directly in front of it.
Run the pump during windy periods. Wind concentrates leaves on the downwind side of the pool. If your skimmer is positioned on that side (as it should be — builders typically install it there), running the pump during and after windy conditions captures the concentrated debris efficiently.
Increase pump run time by 1-2 hours during fall to account for the additional filtration demand from organic debris.
Recovery: When Leaves Have Already Accumulated
If you've fallen behind and the pool has a layer of leaves on the bottom:
- Skim the floating debris first. Remove surface leaves before they sink.
- Vacuum the bottom to waste. Don't send a heavy leaf load through the filter — it'll clog immediately. Use the waste setting on your multiport valve to bypass the filter and send the vacuum discharge to the waste line.
- Check the pump strainer and impeller for leaf fragments. Clear any blockages.
- Clean the filter — even if you vacuumed to waste, some debris made it through during normal operation.
- Test and shock. The decomposing leaves consumed chlorine and introduced phosphates. Test your FC (it's probably low) and shock to restore sanitation. Test phosphates if you have a test kit for them.
- Brush the floor where leaves were sitting. Look for tannin stains. If stains are visible, apply granular shock directly to the stain and let it sit for 30 minutes before brushing again.
The Fall Maintenance Calendar for Murphy
October 1-15: Trim overhanging branches. Install leaf net if using one. Increase pump run time by 1-2 hours. Begin checking skimmer basket every 2-3 days instead of weekly.
October 15-November 30: Peak leaf drop period. Empty leaf net every 3-4 days. Skim daily if not using a net. Clean filter when pressure rises 8+ psi above baseline. Maintain chlorine at 2-3 ppm — don't let it slide just because swimming season ended.
December 1-15: Leaf drop tapers off. Remove leaf net. Do a thorough vacuum of the pool bottom. Deep clean the filter. Inspect the pool for tannin stains and treat as needed. Transition to winter maintenance schedule.
